Covalent bonds are stronger than ionic bonds. With an ionic bond one element has a negative charge (anion) and the other has a positive charge (cation). A trick to remember which is positive and which is negative is that the cation as a t in it, which looks like a + sign, which ...
Covalent organic frameworks (COFs) have unique advantages because of their regular pore structure and large specific surface area, which can anchor ionic sites at specific positions. Yin et al. utilized covalent imidazolium-based ionic liquids with exposed hydroxyl sites in the pores of COF for CO2...
Summary Ionic compounds contain ionic bonds formed by the attraction of oppositely charged ions. Ions in a ionic compound are arranged in repeating patterns known as a crystal lattice. Ionic compounds properties are related to ionic bond strength. Ionic compounds are electrolytes; they conduct an ele...
